SPECIFICATION forming part of Letters Patent No. 705,030, dated July 22, 1902. Application filed May l0, 1901. Serial NoI 59,588. (No model.)

To all whom it' may concern:

Be it known that I, WILLIAM F, BROWN, a citizen of the United States, residing at Athe city of Dowagiac, in the county of Cass and State oflMichigan, have invented certain new and useful Improvements in Shoes for Grain- Drills, of which the following is a specification.

This invention relates to improvements in shoes for grain-drills.

The object of the invention is to provide a shoe for a grain-drill which is easily detachable, the same being so constructed that it is very simple, with scarcely any additional parts, and at the same time the shoe is retained as securely in position as by the usual rivets.

Minor objects will appear in the detailed description to follow.

I accomplish these objectsby the devices and means described in this specification.

The invention is clearly deli'ned and pointed out in the claims.

A structure embodying my invention is clearly illustrated in the accompanying drawings, forming a part of Vthis specification, in whichm- Figure 1 is a side elevation cfa graindrill shoe with its boot attached. Fig.A 2 is a vertical detail sectional view taken on line 2 2 of Fig. l. Fig. 3 is a vertical detail section al view taken on line 3 3 of Fig. 2.

In the drawings all of the sectional views are taken looking in the direction of the little arrows at the ends of the section-lines.

Similar letters of reference referto similar parts throughout the several views.

Referring to the lettered parts of the drawings, A is the boot, and B is the shoe. The shoe is constructed in theusual form from two plates .of metal, the lower edges of which are welded together and an upper rear portion of which is left open like a V. The lower end of the boot A extends forwardly into akind of bracket,and this extends downwardly in a piece somewhat Wedge-shaped A vertical slot A is in this wedgeshaped part, and a bolt C, having an eye C at its lower end, which is pivoted on a rivet or pivot C, through the sides of the shoe I3.

A shoulder A' is on both sides above the wedge-shaped portions A', against which the side plates of the shoe B rest. The slot A engages the'eye C of the bolt C quite closely to prevent a forward-and-backward Inove- Inent of the shoe. A screw-threaded nut is 4 ou the upper end of the bolt Cand fits against a suitable seat to draw the shoe up against the boot, so that when this bolt Cis tightened the shoe is drawn into position and the wedgeshaped portion A crowded into the V-shaped opening in the top of theshoe, and the shoe is retained securely in position and at the same time is easily removed by loosening a single bolt.

The shoes of grain-drills `wear out, and it is consequently very desirable to renew the same or to remove them forthe purpose of sharpening.

Having thus describedmyinvention, what I claim as new, and desire to secure by Letters Patent, is-- l. The combination of the boot A with a Awedge-shaped portion A at the lower end thereof having suitable shoulders A above and a vertical slot AH therein; and a shoe B with a V- shaped opening between its side plates; and a bolt C with an eye Cl embracing a pivot C through the shoe, the said eye C" iitting the said slot closely said bolt errtending upwardly through the part A' of the boot A.

The combination of a boot having a wedge-shaped portion at the bottom with a slot therein; a shoe with side plates forming a tl-shaped opening above to embrace the wedge-shaped part of said boot; a bolt se= cured to a suitable pivot between the sides of the shoe and extending upwardly through the wedge-shaped part ofthe boot,- for the purpose specified.

3. The lcombination of a bootwith a suit able wedge-shaped portion at the bottomcontaining the vertical slot; and ashoe, the side plates of which form a V-shaped opening above to embrace the wedge-shaped portion of said boot, and a bolt connected with the' shoe and extending upwardly for attaching the same to the boot, as specified.

4L. The combination. of a boot with a suitn -able Wedge-shaped portion at the bottom; In witness whereof I have hereunto set my rt/nd shoe, the side plates of which form a hand and seal in the presence of two Witnesses.

s a ed opening above to embrace the Wedge-Shaped portion of said boot; and a bolt WILLIAM F' BROWN' [L' S] connected with the shoe and extending upi Witnesses:

Wardly for attaching the same to the boot, as C. L. FOWLE,
